IMPROVED REFRIGERATOR.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it ma/y concern.-

Be it known that we, SnIEoN WHEAT, of Middle` town,`in the county of Orange, and State of NewYork,

and DAVID B. WHEAT, of the city, county, and State y .maire and use the saine, reference being had to the accompanying drawings, forming part of this specification.

Figure lis a vertical section of our improved re' frigerator, parts being broken away to show'the construction.

Figure '2 is a front View of the same; Figure 3 is a detail sectional view of the drip-pan. Similar letters of reference indicate corresponding parts.

Our invention has for its object to finnish an iinproved refrigerator, which shall be simple in construcf tion, 'and effectiveV in operation, preserving the provisions or other substances placed in it for a longer time, and with a smaller supply of ice, than is possible when the refrigerator is 'constructed ink the ordinary manner;

and'

It consists in the construction and arrangement of various parts, as hereinafter more fully described.

A isthe body of the refrigerator, the walls of which vare made double, and the space between said walls filled with powdered charcoal, or some other nonconducting v substance, in the ordinary manner.

The doors a also enable the ice to be put into the ice-box conveniently.

C is the waste-pipe, by which the water formed b the melting of the ice' is carried off.

The pipe O passes down through the bottom of the refrigerator, and its lower end enters a cup, D, or section of a lagger pipe, through a hole in the side, or over the top of which, the water escapes into a receiver prepared forits reception, said .outletv being at ahigher level than the lower end of the pipe C, so that the said lower end of the said pipe C lmay always be belowthe surface of the water in the cup D, thus preventing the entrance of air to the ice-box through the waste-pipe 0.

E is adrip-pan, which is made of a size equal to or a little larger than the bottom of the vice-box Bh so that it may receive the drip or water condensed upon vthe outer surface of the-ioe-box The water from the pan E passes into the waste pipe O through the small pipe ef, as shown in .gz 3.

The upper shelf, F, should be at or a little above the level of the bottomof the ice-box B, and .its parts are hinged, so that they may be turnedy up out of the way, when it is necessary to place an article in the refrigerator which may be of a greater height than the space between the shelves. The forward part of the middle portion of the cen- `tral shelf, G, is out away, to allow the air cooled by contact with the ice-box to descenld, to co'ol the articles Aplaced upon the' bottom of the refrigerator A, which said bottom forms the lower shelf'.

Hare Ventilating-pipes, which are placed in the anglesiof the inner Walls of the refrigerator, at its rear side, as shown in iig. 1, so as to be entirely out ofthe. way, and which pass up through the top of the refrigerator, as shown in dotted lines inv g. 1.

The lower ends, or the inner openings of the pipes H, 'are below the central shelf G, and near the bottom of the refrigerator, so that as `the air cooled-'by the ice -descends through the opening in the shelf G, the warm airgmay pass or be forced into and escape through the pipes H.

lIhe interior surface of the bodyA of the refrigera- I ton is lined or coated with a` coating, K, of plaster .of

Paris, as shown in iig. 1, so as to more fullyfprotect the articles placed in said refrigerator from the action of the surrounding atmosphere.

Access is obtained to the interiorof the refrigerator through the doors I, the central one of which is made of such -a height as not'to reach quite to the level of the bottom of the ice-box B, as shown in the drawings.

In the lower parts of the side doors I are formed ventilating-o'penin gs, provided with wire-gauze screens, and closed upon the inner sides of said doors by slides J, as shown in dotted lines in fig. 2, so that the ventilation ofthe refrigerator may be regulated as circumstances may require. J

Having thus described our invention, 'y

VWe claim as new, and desire to secine by Letters Patent- Witnesses:V Y
